Mini updates 3 - PC98 A-Train III, Atari ST keyboard fix, FM-7 video adapter

Some more mini updates for things that weren’t big enough to merit a full update on their own. In this entry, we’ll finally get A-Train III running on my PC98, fix an Atari ST keyboard, and ship new hardware for a whole new brand of Japanese 8-bit computer.

The PC98 can remember lots of things

Just as I was beginning to lose hope that the hard drive I had ordered back in August from Yahoo Auctions Japan would ever arrive, my doorbell rang. Inside a beat-up but functional Suruga-ya box sat the hard drive, done with its international journey.

PC98 - New floppy board, sound 'fixed,' more testing

Floppy adapter board works for the PC98!

After I designed the first version of my PC88 floppy board, I thought it would be fun to put one together for the PC98 as well. Why do I need an adapter for a computer that already has 3.5” floppy drives? The PC9821AP2 I own has a 26-pin floppy drive connector, like a mid-90s laptop, and most standard IBM PC style floppy drives have 34.

PC9821AP2/U8W - day one

Months ago, I won a PC8801mkII and a PC9821AP2/U8W off Yahoo Auctions. They arrived, but life got busy, and so the blog hasn’t been updated in quite some time. What better way to bring it back than a deep-dive into a computer whose language I literally do not speak or understand in even the slightest way?
